Razor

2 Claims.

My invention is an improvement in razors of that special type commonly known as an ordinary razor in contradistinction to a safety razor, and of that class in which the razor blade is separate from the back or holder for the blade.

Notwithstanding the extensive use of safety razors there are many who prefer an ordinary razor on account of its easier manipulation, and to provide a cutting edge free from the difiiculties of honing and stropping it is now a common expedient to have a detachable blade which may be purchased separately as provided for by the different forms of safety razors. To this end the conventional form of improved ordinary razor is of that type in which a thin blade is slidable longitudinally in a holder pivotally connected by a shank to the razor handle.

With this form of razor in mind my invention contemplates the production of a blade of peculiar shape whereby it will cooperate with the holder in such a manner as to not only permit of said blade being firmly held in place for use but will facilitate removal in replacing new blades or for cleaning the blade and holder after shaving.

With these principal objects in view my invention consists of a holder having a longitudinal recess and clamping jaws at opposite sides thereof in combination with a blade having spaced apart curved members at its inner edge adapted to fit within the recess in the holder to augment the clamping action of the jaws, as hereinafter described and more specifically set forth in the appended claims.

In the drawing forming a part of this specification:

Figure 1 is a perspective View of a razor constructed in accordance with my invention.

Fig. 2 is an enlarged detail view of the holder, in side elevation, a part thereof being broken away to show the means for attachment of the blade.

Fig. 3 is an end view of the holder with the blade in place.

Fig. 4 is a longitudinal sectional view through the holder, the blade being indicated in dotted lines.

Fig. 5 is a. sectional view on the line 55 of Fig. 4.

Fig. 6 is a detail perspective View of the blade, and

Figs. 7 and 8 are transverse sectional views on the lines '|l and 88 of Fig. 2.

In carrying out my invention the improved form of blade I0 is used in connection with a back piece or holder II having a shank l2 by which it is pivoted at l3 between the inner ends of the two-part handle M, the parts or sides of the handle being spaced to receive the blade and holder, in closed position of the razor, by the aforesaid shank and a filling piece H) at the outer end of the handle.

The holder II is in the form of a metal piece formed integral with the shank and provided with a circular hole or recess l6 extending inwardly from the outer end of the holder longitudinally 10 on a line with the shank, said circular recess being of a depth equal to the length of the razor blade, and communicating with this longitudinal recess at its lower end is a vertical slot ll dividing the lower portion of the holder into clamping 15 members l8, l8. It will be noted by reference to Figs. 2 and 3 that the recess l6 terminates a little in advance of the rear end of the holder proper and that the slot I'l opens out at said rear end of the holder so as to not interfere with the resiliency of the clamping members or jaws l8, and by reference to Fig. 5 it will be understood that the space between said jaws in their normal position, or before the insertion of the blade hereinafter particularly described, is slightly less than the thickness of the blade for the necessary clamping of the latter within the holder.

In addition to the special construction of holder hereinbefore described I employ a blade of peculiar shape so that it will more effectively cooperate with said holder when the assembly is made; that is to say although the holder may receive an ordinary type of removable blade having a curved back extending its full length I have discovered an improved form, for a holder of the character described, in which the blade has spaced apart curved members l9, I9 and 20 serving to hold it more firmly within the holder, and facilitating the operation of inserting the blade 40 as well as removing it for cleaning, etc. Another important advantage of having spaced apart members engaging the circular recess in the holder is that this arrangement readily cooperates with the clamping jaws in providing a slightly yielding blade structure adding to the comfort in shaving with this type of razor. The slight yielding of the blade structure is also induced by the thinness of the jaws and the fact that they taper to a fine or feather edge at opposite sides of the blade, which is also a desideratum in the operation of honing or stropping the razor.

The spaced apart curved members or short ribs l9 and 20 are preferably three in number,

one at each end of the blade, designated by l9, and the third at the center, designated by 20, and by experimentation I have found that better results are attained by having the members at the ends of the blade in a complete circle or tubular while the member 20 at the center is in the arc of a circle, as shown in the detail view, Fig. 6 of the drawing. These members or ribs not only augment thejaws in holding the blade within the holder by frictional or binding contact but serve also to stiffen the blade as a unit without adding materially to the expense of the same. However, it Will be understood that the crosssectional shape of the spaced apart reinforcing members or ribs at the rear edge of the blade may be modified or changed Without departing from the scope of my invention, but by having short tubular ribs at the ends and an arcuate rib at the center the stability aiiorded thereby does not affect the slight resiliency desirable in the manipulation of the blade while shaving or during the operations of honing and stropping.

I claim:-

1. A razor comprising a blade holder connected to a handle, said holder having a longitudinal recess and a communicating longitudinal slot extending coincidentally the full length of the body of the holder to provide resilient clamping members or jaws tapered from the recess to the outer edge of the jaws; together with a blade having short tubular ribs at the ends of the rear edge thereof and an arcuate rib at the center. said ribs being adapted to fit within the longitudinal recess of the holder with the body of the blade clamped between the jaws, those portions of the blade between the ribs augmenting the resiliency of the razor.

2. A razor blade having spaced apart short ribs at the ends and center of the back edge thereof opposite the cutting edge for attachment of the blade to a blade holder, the ribs at the ends of the blade being circular in cross section and the rib at the center being substantially semi-circular in cross section, whereby the ribs being spaced apart and including a semi-circular rib at the center provide for the resiliency of said blade when attached to a blade holder.
